python3环境下，为什么在apache2部署django会出现UnicodeEncodeError？

Question

部署环境：
ubuntu server 16.04
apache2
python 3.6.2 (使用conda虚拟环境)
django 1.11

我在django的views.py代码里有这么一句:

    filepath = settings.PART_MESSAGE_FILEPATH + '/' + file.name

    with open(filepath, 'wb+') as new_file:
        for chunk in file.chunks():
            new_file.write(chunk)

当这个文件的名字包含中文时，就会报错，在apache的errorlog上会留下这样的记录.
文件名不包含中文的时候，就一切正常

我的conf文件

<VirtualHost *:7090>

    ServerName localhost:7090
    ServerAdmin [e-mail]


    WSGIDaemonProcess comengine python-path=/home/yangtz/anaconda3/envs/compoengine/lib/python3.6/site-packages


    WSGIProcessGroup comengine

    WSGIScriptAlias / /data2/serverend/comengine/comengine/wsgi.py


    #Directory里是项目wsgi文件的父目录，形如：/项目所处路径/dpsplat/visualplat
    <Directory /data2/serverend/comengine/comengine>
    <Files wsgi.py>
        Require all granted
    </Files>
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error-comengine.log
    CustomLog ${APACHE_LOG_DIR}/access-comengine.log combined

</VirtualHost>

我的环境明明是python3.6啊，怎么会出现UnicodeEncodeError呢？在本地runserver的时候就不会有这种事，部署到服务器 apache上就会这样，这是怎么回事？该怎么办呢？

Answer 1

问题已经解决了。

Answer 2

ascii表中是不包括中文的, 先encode成utf-8吧

Answer 3

python3虽然统一了字符串 str 的语义，并且默认采用 utf-8 的编码。但也不意味着没有编码出错的情况。你的文件应该是win下的文件，因此名称应该是win的 cp396 的，用 .encode("cp936").decode("utf-8") 吧。

Answer 4

看下你平台默认的是啥：

 In text mode, if encoding is not specified the encoding used is platform
 dependent: locale.getpreferredencoding(False) is called to get the
 current locale encoding.
